time: three years from October 2005.
GdR MOMAS - Numerical models for nuclear waste disposal
The working group MOMAS is led now by A. Ern from CERMICS and includes many partners from CNRS, INRIA, universities, CEA, ANDRA, EDF and BRGM. It covers many subjects related to mathematical modeling and numerical simulations for nuclear waste disposal problems. We participate in the project entitled ``Numerical and mathematical methods for reactive transport in porous media''  ,  . See sections 6.2.3 , 4.1 .
HydroGrid - Multiphysics models in hydrogeology
HydroGrid: Coupling codes for flow and solute transport in geological media: a software component approach.
ACI GRID grant, No. 102C07270021319
time: from October 2002 until February 2006
Coordinator: M. Kern, Estime Inria team
Participants: Paris Irisa team, Estime Inria team, Sage Irisa team, IMFS (U. of Strasbourg), CAREN (U. of Rennes 1).
The final report of the project was presented in February. We have worked on three applications: saltwater intrusion  , reactive transport  ,  and 3D network of fractures  . See sections 6.2.3 , 6.4.3 . We have developed parallel software components and run experiments on the grid at Irisa  . Wa have also developed the software GRIDMESH for generating a regular mesh  . See section 5.3 .
ACI GRID program GRID'5000, two projects entitled Grille Rennes
time: three years from 2003 and three years from 2004. Coordinator : Y. Jégou, Paris team, INRIA-Rennes.
Software platform for numerical simulations in hydrogeoloy
BQR from the University of Rennes 1
Participants : Sage team and Geosciences department.
We aim at developing a platform, called Hyrolab, integrating our different modules for simulating flow and solute transport in porous and fractured media  . We have organized the software in well-defined components, tested the simulations on both Windows and Linux systems, created a project in the Inria Gforge and created a subversion repository. See sections 3.2 , 4.1 , 5.6 , 6.4.2 , 6.4.3 .

Title : Numerical model for the propagation of elastic waves
time : from January 2006 until March 2007.
This work is done in the context of the ``Contrat de Plan Etat Région Bretagne 2000-2006'' (signed in October 2002 – it contains five parts and is spread out over the period 2002-2007), for the development of new geophysical exploration means.
The first objective of this study was to develop a software simulating the propagation of elastic waves in the seawater and in the underwater geophysical layers. We have used the code FLUSOL from the INRIA-team ONDES. The second objective is to study inverse methods to find layer properties in the ground, only from acoustic measurements recorded near the sea surface by a ship. The reflection of the wave at each interface allows us to collect information in the fluid and, via appropriate numerical methods, to determine the density and the elasticity of each layer constituting the solid sub-marine soil  ,  ,  ,  . See sections 4.1 , 6.3.1 .
